8 Facts About Dog Breeds Backed By Science

8 Facts About Dog Breeds Backed By Science

“A dog has the soul of a philosopher.” – Plato

Are you one of the 70% of people who sign their pet dog’s name on greeting cards? No need to confess, just read on! Did you know that three dogs actually survived the Titanic? They were a Newfoundland, a Pomeranian and a Pekingese. I do not know what was in their genetic makeup which helped them do that. Maybe they were just lucky.

So, are dog breeds all different? What role does genetics, training and the dog’s own personality play in determining whether they are indeed man’s best friend? Let us look at 8 facts which are backed by science which will help us understand this better.

1. Belgian shepherd dogs can sniff out cancer and other diseases

It is generally known that dogs have an extremely acute sense of smell, about 100,000 times sharper than ours. Scientific studies have been done on the Belgian shepherd dogs (the Malinois) which have shown that they can detect prostate cancer in men. These dogs were able to correctly detect the cancer by sniffing urine samples.

Apparently cancer cells leave a particular odor which these dogs can pick up, after training. They got 63 out of 66 right! These studies were conducted by a French researcher and were presented at a conference organized by the American Urological Association.

2. Border collies, poodles and German shepherds are the most intelligent dogs

If you ever wanted a really intelligent dog as a pet, choose one of the above. These dogs are actually as clever as a two year child and they can process up to 165 different gestures, movements and words. Not bad for a dog. The Afghan hound comes at the bottom of the list as being pretty dumb. These findings were the result of research carried out by a canine researcher, Dr. Stanley Coren, of the University of British Columbia.

3. There’s selective breeding for tailor made dogs

Consumer tastes and dog breeders have collaborated in producing dog breeds which meet market demands. This is why we have hunting dogs, sociable dogs and guard dogs. The only problem here is that the inbreeding leads to many dogs having typical diseases which are now very hard to eliminate.

Golden retrievers are more liable to get cancer while King Charles spaniels may have more heart diseases. Experts say that pugs could be bred to have larger muzzles so that they do not suffer from respiratory diseases, like they do now.

4. A special dog breed is supposed to help autistic children

A cross breed of the golden retriever and poodle (the golden doodle) is now being bred to help children with autism (ASD). They have been incredibly successful in that the kids’ sleeping patterns and general behavior have improved by leaps and bounds. This new breed of dog combines the star qualities of both in that they are friendly, patient, loyal and above all forgiving when the kids give them a rough time. These dogs have enriched the lives of autistic children and helped them to lead more normal lives.

5. Chocolate can kill a dog

Chocolate can make your dog very sick or even kill him or her. An 8 lb. pound poodle was fed one pound of chocolate on her birthday and nearly died. If you feed a golden retriever who weighs about 60 pounds with a bag of Hershey kisses, then the effects will be much less severe. The problem is that chocolate contains theobromine which is toxic for dogs. Another bad idea is to feed a dog with apple or pear seeds as these contain arsenic which can also be fatal for dogs.

6. The Newfoundland is the best swimmer

This breed of dog is known for its webbed feet and strong swimming skills. It is no surprise to learn that it was first used to help fisherman in Newfoundland to pull in their nets and also in helping to haul back wood from the forests. They have a double waterproof coat which helps them survive in icy waters. They are strong, loving, courageous, and loyal. They make great guard dogs, too. The only problem is that they adore water and mud which can make them a difficult home pet.

7. Moscow stray dogs

These 35,000 feral dogs are famous for many reasons. One is that they have become much smarter at getting people to drop their snacks just bought at the food kiosks. They sneak up and bark at the customer who, startled, drops it and the dog gobbles it up. This is known as “the hunt for shawarma”.

Another incredible thing is that these dogs have become adept at travelling on the subway to get from one part of the city to the other. They seem to possess an inbuilt sense of timing to know when to get off at the right metro stop! They are also better behaved on the metro than they are on the streets when hunting down food. Biologists, such as Andrei Poyarkov, who have studied these dogs noticed that they have learned how to cross streets by using the traffic lights. They have also adapted to the continually evolving Russian capital.

8. Dogs who look like wolfs live longer

Generally, dogs live about 15 years but this does vary according to the size and face features of whichever breed we are talking about. Bulldogs and pugs who have flat muzzles tend to live shorter lives. Those who look more like their wolf ancestors with sharp, pointed features will live longer. This is just one of the fun facts mentioned in Planet Dog: A Doglopedia by Sandra and Harry Choron. The longest living dog was a Queensland Heeler called Bluey who lived to the ripe old age of 29 years and 5 months.

12 Best Brain Foods That Improve Memory and Boost Brain Power

12 Best Brain Foods That Improve Memory and Boost Brain Power

Nutrition plays a vital role in brain function and staying sharp into the golden years. Personally, my husband is going through medical school, which is like a daily mental marathon. Like any good wife, I am always looking for things that will boost his memory fortitude so he does his best in school.

But you don’t have to be a med student to appreciate better brainiac brilliance. If you combine certain foods with good hydration, proper sleep and exercise, you may just rival Einstein and have a great memory in no time.

I’m going to reveal the list of foods coming out of the kitchen that can improve your memory and make you smarter.

Here are 12 best brain foods that improve memory:

1. Nuts

The American Journal of Epidemiology published a study linking higher intakes of vitamin E with the prevention on cognitive decline.[1]

Nuts like walnuts and almonds (along with other great foods like avocados) are a great source of vitamin E.

Cashews and sunflower seeds also contain an amino acid that reduces stress by boosting serotonin levels.

Walnuts even resemble the brain, just in case you forget the correlation, and are a great source of omega 3 fatty acids, which also improve your mental magnitude.

2. Blueberries

Shown in studies at Tuffs University to benefit both short-term memory and coordination, blueberries pack quite a punch in a tiny blue package.[2]

When compared to other fruits and veggies, blueberries were found to have the highest amount of antioxidants (especially flavonoids), but strawberries, raspberries, and blackberries are also full of brain benefits.

3. Tomatoes

Tomatoes are packed full of the antioxidant lycopene, which has shown to help protect against free-radical damage most notably seen in dementia patients.

4. Broccoli

While all green veggies are important and rich in antioxidants and vitamin C, broccoli is a superfood even among these healthy choices.

Since your brain uses so much fuel (it’s only 3% of your body weight but uses up to 17% of your energy), it is more vulnerable to free-radical damage and antioxidants help eliminate this threat.

Broccoli is packed full of antioxidants, is well-known as a powerful cancer fighter and is also full of vitamin K, which is known to enhance cognitive function.

5. Foods Rich in Essential Fatty Acids

Your brain is the fattest organ (not counting the skin) in the human body, and is composed of 60% fat. That means that your brain needs essential fatty acids like DHA and EPA to repair and build up synapses associated with memory.

The body does not naturally produce essential fatty acids so we must get them in our diet.

Eggs, flax, and oily fish like salmon, sardines, mackerel and herring are great natural sources of these powerful fatty acids. Eggs also contain choline, which is a necessary building block for the neurotransmitter acetylcholine, to help you recall information and concentrate.

6. Soy

Soy, along with many other whole foods mentioned here, are full of proteins that trigger neurotransmitters associated with memory.

Soy protein isolate is a concentrated form of the protein that can be found in powder, liquid, or supplement form.

Soy is valuable for improving memory and mental flexibility, so pour soy milk over your cereal and enjoy the benefits.

7. Dark chocolate

When it comes to chocolate, the darker the better. Try to aim for at least 70% cocoa. This yummy desert is rich in flavanol antioxidants which increase blood flow to the brain and shield brain cells from aging.

8. Foods Rich in Vitamins: B vitamins, Folic Acid, Iron

Some great foods to obtain brain-boosting B vitamins, folic acid and iron are kale, chard, spinach and other dark leafy greens.

B6, B12 and folic acid can reduce levels of homocysteine in the blood. Homocysteine increases are found in patients with cognitive impairment like Alzheimer’s, and high risk of stroke.

Studies showed when a group of elderly patients with mild cognitive impairment were given high doses of B6, B12, and folic acid, there was significant reduction in brain shrinkage compared to a similar placebo group.[3]

Other sources of B vitamins are liver, eggs, soybeans, lentils and green beans. Iron also helps accelerate brain function by carrying oxygen. If your brain doesn’t get enough oxygen, it can slow down and people can experience difficulty concentrating, diminished intellect, and a shorter attention span.

To get more iron in your diet, eat lean meats, beans, and iron-fortified cereals. Vitamin C helps in iron absorption, so don’t forget the fruits!

9. Foods Rich in Zinc

Zinc has constantly demonstrated its importance as a powerful nutrient in memory building and thinking. This mineral regulates communications between neurons and the hippocampus.

Zinc is deposited within nerve cells, with the highest concentrations found in the hippocampus, the part of the brain responsible for higher learning function and memory.

Some great sources of zinc are pumpkin seeds, liver, nuts, and peas.

10. Gingko biloba

This herb has been utilized for centuries in eastern culture and is best known for its memory boosting brawn.

It can increase blood flow in the brain by dilating vessels, increasing oxygen supply and removing free radicals.

However, don’t expect results overnight: this may take a few weeks to build up in your system before you see improvements.

11. Green and black tea

Studies have shown that both green and black tea prevent the breakdown of acetylcholine—a key chemical involved in memory and lacking in Alzheimer’s patients.

Both teas appear to have the same affect on Alzheimer’s disease as many drugs utilized to combat the illness, but green tea wins out as its affects last a full week versus black tea which only lasts the day.

12. Sage and Rosemary

Both of these powerful herbs have been shown to increase memory and mental clarity, and alleviate mental fatigue in studies.

Try to enjoy these savory herbs in your favorite dishes.

When it comes to mental magnitude, eating smart can really make you smarter. Try to implement more of these readily available nutrients and see just how brainy you can be!
